On second thought, we'd better just drop these tests altogether.
Further experimentation reveals that my previous change didn't fix the
issue entirely: these tests would still fail at the spring-forward DST
transition. There doesn't seem to be any great value in testing this
specific issue for both timestamp and timestamptz, so just lose the
latter tests.
